This is an SAT question of the day that I can't understand.
The sum of the digits of a three-digit number is 12. If the hundreds digit is 3 times the tens digit and the tens digit is 1 over 2 the units digit, what is the tens digit of the number?
Answer choices:
2
3
4
6
9

    I don't know what 1 over 2 the units digit means.

  • math -

    I don't know either. Could it just mean 1/2 more than the tens digit?

  • math -

    Let the digits be H, T and U
    H + T + U = 12
    H = 3T
    T = (1/2) U
    4T + 2T = 12
    T = 2
    T is the tens digit
